This has running through my head for a while, I've the asked the question to a few, but havn't really gotten an exact answer.
Basically, what is classified as a legal trail? Any existing fire trail/bush walk trail?
The reason I ask, is being an avid bushwalker as well, there are plenty of trails (mainly fire trails) that exist, that I know, and would be suitable for mountain biking. For example, there is a series of trails that mates from our workplace, ride on a monthly basis in mundaring, we have been seen by various council officials etc. that haven't approached us for infringements etc.
Are we simply not allowed to go off the beaten path as such, without prior authorization? Something needs to to written up for clarification by the relevant government bodies, as currently nothing seems to exist.
